The Micronesian Kingfisher, Todiramphus cinnamominus, was found on three islands or island groups, Guam, Pohnpei, and Palau. The birds of each island are considered subspecies, although some authorities consider each full species. The nominate species T. c. cinnamominus (image above) was found on the island of Guam but became extinct in the wild because of the disastrous introduction of the Brown Tree Snake. It still survives in captive breeding programs and there are hopes of re-introducing it to suitable areas in Guam.

There are currently about 100 individuals of the Guam subspecies in captive breeding programs. Two factors which are discouraging towards successful re-introduction are low breeding success and the continued presence of the Brown Tree Snake in the natural habitat.
